Section 51-18-07 - Buyer responsibility - Services1. Except as provided in subsection 3 of section 51-18-05, within twenty days after a personal solicitation sale has been canceled, the buyer upon demand shall tender to the seller any goods delivered by the seller pursuant to the sale, but the buyer is not obligated to tender at any place other than the buyer's own address. If the seller fails to take possession of such goods within twenty days after cancellation, the goods become the property of the buyer without obligation to pay for them.2. The buyer shall take reasonable care of the goods in the buyer's possession both prior to cancellation and during the following twenty-day period. During the twenty-day period after cancellation, except for the buyer's duty of care, the goods are at the seller's risk.3. If the seller has performed any services pursuant to a personal solicitation sale prior to its cancellation, and if the seller's services result in the alteration of property of the buyer, the seller shall restore the property to substantially as good condition as it was in at the time the services were rendered.4. The buyer may not cancel a personal solicitation sale if the buyer initiates the contract with the seller and requests the seller to provide goods or services without delay and the seller in good faith makes a substantial beginning of performance before notice of cancellation, and the goods cannot be returned to the seller in substantially as good condition as when the buyer received them.
